In an effort to learn what I can about it before tearing it down and having the machine shop give it the old once over I wrote down the serial numbers and the casting numbers. The casting nos. tell me it's a 250 from 66-84 the particularly 73 or 83. I know so little about 6s that I couldn't tell you the difference between the two if it was stamped on the valve cover. So can anybody glean anything from these:

I appreciate your help.
Thanks- Andy | | |
